Question details

4)0.5A fuse on DI880(TU810) main supply and Also 0.5A each 16 channels(some how when our field wire short it blown main fuse not channel fuse) please tell me the max tolerable Current rating on each channel

5)0.5A fuse on DO880(TU810) main supply(we use realy on each 16 channel output (each relay load is 42.5mA))

Hello,

1.PM865 draws a max current of 487mA at 24V Since due to conversion losses when the current supply to module bus & CEX bus the power dissipation increases by 5W hence 487mA+208mA=695mA since we won't get 695mA hence we will put 1A.

2.For SM810:max continuos load current is itself 0.5A So let it be 0.5A Since max short circuit current is <2.4mA

3.For BC810:It draws a max current of 70mA(1.7W) at 24V & its better to put 0.5A.

4.For DI880:It draws a max current of 527mA at 24V, since we won't get 527mA hence we will put 1A.

5.For DO880: It draws maximum continuos load current of 8A/module at 55degc
